目的：通过９９ＴｃｍＯ４－标记的固体餐检测胃排空，了解小儿慢性胃炎胃运动的情况．方法：９９ＴｃｍＯ４－标记鸡肝为试餐，对２５例慢性胃炎患儿进行了核素检测分析．结果：轻度慢性胃炎患儿的胃半排空时间为６３．８６ｍｉｎ，９５％可信区间为３７．４９ｍｉｎ～９０．２２ｍｉｎ．中度慢性胃炎患儿的胃半排空时间为９５．６８ｍｉｎ，９５％可信区间为７１．８８ｍｉｎ～１１９．４９ｍｉｎ，重度慢性胃炎患儿的胃半排空时间大于１２０ｍｉｎ．结论：小儿慢性胃炎患儿的胃排空时间随病情加重而延长，不同程度病变间有显著差异．
OBJECTIVE: To detect gastric emptying by 99TcmO4-labeled solid meal to understand the situation of gastric motility in children with chronic gastritis. Methods: 99TcmO4-labeled chicken liver as a test meal, 25 cases of chronic gastritis in children with radionuclide detection analysis. Results: The gastric emptying time of children with mild chronic gastritis was 63.86min, 95% confidence interval was 37.49min ~ 90.22min. Gastric half-emptying time in children with moderate chronic gastritis was 95.68min, the 95% confidence interval was 71.88min ~ 119.49min, and the gastric half-emptying time in children with severe chronic gastritis was more than 120min. Conclusion: The gastric emptying time in children with chronic gastritis is prolonged with the aggravation of the disease, and there are significant differences among different degrees of lesion.
